[0035] FIG. 1 is a schematic block diagram of a video display device according to an embodiment of the present disclosure.

[0036] Referring to FIG. 1, a video display device (100) according to an embodiment of the present disclosure may include a broadcast receiving unit (105), an external device interface unit (135), a storage unit (140), a user input interface unit (150), a control unit (170), a display unit (180), an audio output unit (185), a power supply unit (190), and a photographing unit (not shown). The broadcast receiving unit (105) and the external device interface unit (135) may be collectively referred to as a communication unit.

[0037] The broadcast receiving unit (105) may include a tuner (110), a demodulator (120), and a network interface unit (130). Of course, if necessary, it may be designed to include a tuner (110) and a demodulator (120) but not a network interface unit (130), and conversely, it may be designed to include a network interface unit (130) but not a tuner (110) and a demodulator (120).

[0038] The tuner (110) selects an RF broadcast signal corresponding to a channel selected by the user or all pre-stored channels among RF (Radio Frequency) broadcast signals received through an antenna. In addition, it converts the selected RF broadcast signal into an intermediate frequency signal or a baseband video or audio signal.

[0039] For example, if the selected RF broadcast signal is a digital broadcast signal, it is converted into a digital IF signal (DIF), and if it is an analog broadcast signal, it is converted into an analog baseband video or audio signal (CVBS / SIF). That is, the tuner (110) can process both digital broadcast signals and analog broadcast signals. The analog baseband video or audio signal (CVBS / SIF) output from the tuner (110) can be directly input to the control unit (170).

[0040] Additionally, the tuner (110) can receive an RF broadcast signal of a single carrier according to the ATSC (Advanced Television System Committee) method or an RF broadcast signal of multiple carriers according to the DVB (Digital Video Broadcasting) method.

[0041] Meanwhile, the tuner (110) can sequentially select RF broadcast signals of all broadcast channels stored through a channel memory function among RF broadcast signals received through an antenna and convert them into intermediate frequency signals or baseband video or audio signals.

[0042] The demodulation unit (120) receives a digital IF signal (DIF) converted by the tuner (110) and performs a demodulation operation.

[0043] For example, if the digital IF signal output from the tuner (110) is in ATSC format, the demodulation unit (120) performs, for example, 8-VSB (8-Vestigal Side Band) demodulation. In addition, the demodulation unit (120) may also perform channel decoding. To this end, the demodulation unit (120) may be equipped with a Trellis Decoder, a De-interleaver, a Reed-Solomon Decoder, etc., and may perform Trellis decoding, deinterleaving, and Reed-Solomon decoding.

[0044] For example, if the digital IF signal output from the tuner (110) is in the DVB format, the demodulation unit (120) performs, for example, COFDMA (Coded Orthogonal Frequency Division Modulation) demodulation. In addition, the demodulation unit (120) may also perform channel decoding. To this end, the demodulation unit (120) may be equipped with a convolution decoder, a deinterleaver, a Reed-Solomon decoder, and the like, and may perform convolution decoding, deinterleaving, and Reed-Solomon decoding.

[0045] The demodulator (120) can output a stream signal (TS) after performing demodulation and channel decoding. At this time, the stream signal may be a signal in which a video signal, an audio signal, or a data signal is multiplexed. For example, the stream signal may be an MPEG-2 TS (Transport Stream) in which a video signal in the MPEG-2 standard and an audio signal in the Dolby AC-3 standard are multiplexed. Specifically, the MPEG-2 TS may include a 4-byte header and a 184-byte payload.

[0046] Meanwhile, the above-described demodulation unit (120) can be provided separately according to the ATSC method and the DVB method. That is, it can be provided as an ATSC demodulation unit and a DVB demodulation unit.

[0047] The stream signal output from the demodulation unit (120) can be input to the control unit (170). The control unit (170) performs demultiplexing, image / audio signal processing, etc., and then outputs the image to the display unit (180) and outputs the audio to the audio output unit (185).

[0108] Meanwhile, unlike the one illustrated in FIG. 1, the video display device (100) does not have the tuner (110) and demodulator (120) illustrated in FIG. 1, and can receive and play video content through the network interface unit (130) or the external device interface unit (135).

[0109] The artificial intelligence-related functions according to the present disclosure can be operated through a control unit and a memory. The control unit may include one or more processors. In this case, one or more processors may be a general-purpose processor such as a CPU, an AP, a DSP (Digital Signal Processor), a graphics-only processor such as a GPU or a VPU (Vision Processing Unit), or an artificial intelligence-only processor such as an NPU. One or more processors may be controlled to process input data according to predefined operation rules or artificial intelligence models stored in the memory. Alternatively, if one or more processors are artificial intelligence-only processors, the artificial intelligence-only processors may be designed with a hardware structure specialized for processing a specific artificial intelligence model.

[0110] Artificial intelligence (AI) is the study of artificial intelligence or the methodologies for creating it, while machine learning (ML) defines various problems in the field of AI and studies the methodologies for solving them. Machine learning is also defined as an algorithm that improves performance on a task through consistent experience.

[0111] An artificial neural network (ANN) is a model used in machine learning. It can refer to a model with problem-solving capabilities, comprised of artificial neurons (nodes) that form a network through the connection of synapses. An ANN can be defined by the connection patterns between neurons in different layers, the learning process that updates model parameters, and the activation function that generates output values.

[0112] An artificial neural network may include an input layer, an output layer, and optionally one or more hidden layers. Each layer contains one or more neurons, and the artificial neural network may include synapses connecting neurons. In an artificial neural network, each neuron can output a function value of an activation function based on input signals, weights, and biases received through the synapses.

[0113] Model parameters are parameters determined through learning, including synaptic connection weights and neuron biases. Hyperparameters are parameters that must be set before learning in machine learning algorithms, including the learning rate, number of iterations, mini-batch size, and initialization function.

[0114] The goal of artificial neural network training can be seen as determining model parameters that minimize a loss function. The loss function can be used as an indicator for determining optimal model parameters during the artificial neural network training process.

[0115] Machine learning can be classified into supervised learning, unsupervised learning, and reinforcement learning depending on the learning method.

[0116] Supervised learning refers to a method for training an artificial neural network when given labels for the training data. The labels can refer to the correct answer (or output value) that the artificial neural network must infer when the training data is input to the artificial neural network. Unsupervised learning can refer to a method for training an artificial neural network when the training data is not given labels. Reinforcement learning can refer to a learning method in which an agent defined within a given environment is trained to select actions or action sequences that maximize the cumulative reward in each state.

[0117] Machine learning implemented with a deep neural network (DNN) containing multiple hidden layers among artificial neural networks is also called deep learning, and deep learning is a subset of machine learning. Hereinafter, the term "machine learning" is used to encompass deep learning.

[0118] Object detection models using machine learning include the single-stage YOLO (You Only Look Once) model and the two-stage Faster R-CNN (Regions with Convolution Neural Networks) model.

[0119] The YOLO (You Only Look Once) model is a model that can predict objects and their locations within an image by looking at the image only once.

[0120] The YOLO (You Only Look Once) model divides the original image into grids of equal size. For each grid, it predicts the number of bounding boxes in a predefined shape centered around the grid center, and calculates a confidence level based on this prediction.

[0121] Afterwards, whether the image contains an object or is just a background is included, and locations with high object confidence are selected so that the object category can be identified.

[0122] The Faster R-CNN (Regions with Convolution Neural Networks) model is a model that can detect objects faster than the RCNN model and the Fast RCNN model.

[0123] This article specifically explains the Faster R-CNN (Regions with Convolution Neural Networks) model.

[0124] First, feature maps are extracted from the image using a Convolution Neural Network (CNN) model. Based on the extracted feature maps, multiple regions of interest (RoIs) are extracted. RoI pooling is performed for each region of interest.

[0125] RoI pooling is a process of setting a grid to a predetermined size of H x W for the feature map onto which the region of interest is projected, extracting the largest value for each cell included in each grid, and extracting a feature map with a size of H x W.

[0126] A feature vector is extracted from a feature map having a size of H x W, and object identification information can be obtained from the feature vector.

[0127] FIG. 2 is a drawing illustrating a control method of a remote control device that controls a video display device according to one embodiment of the present disclosure.

[0128] As shown in (a) of Fig. 2, a pointer (205) corresponding to a remote control device (200) is displayed on the display unit (180).

[0129] The user can move or rotate the remote control device (200) up and down, left and right ((b) of FIG. 2), and forward and backward ((c) of FIG. 2). The pointer (205) displayed on the display unit (180) of the video display device corresponds to the movement of the remote control device (200). As shown in the drawing, the pointer (205) moves and is displayed according to the movement in 3D space, so the remote control device (200) can be called a space remote control.

[0130] Figure 2 (b) illustrates that when a user moves the remote control device (200) to the left, the pointer (205) displayed on the display unit (180) of the video display device also moves to the left in response.

[0131] Information about the movement of the remote control device (200) detected by the sensor of the remote control device (200) is transmitted to the video display device. The video display device can calculate the coordinates of the pointer (205) from the information about the movement of the remote control device (200). The video display device can display the pointer (205) to correspond to the calculated coordinates.

[0132] FIG. 2 (c) illustrates a case where a user moves the remote control device (200) away from the display unit (180) while pressing a specific button within the remote control device (200). As a result, a selection area within the display unit (180) corresponding to the pointer (205) may be zoomed in and displayed in an enlarged manner. Conversely, when the user moves the remote control device (200) closer to the display unit (180), a selection area within the display unit (180) corresponding to the pointer (205) may be zoomed out and displayed in a reduced manner. Meanwhile, when the remote control device (200) moves away from the display unit (180), the selection area may be zoomed out, and when the remote control device (200) moves closer to the display unit (180), the selection area may be zoomed in.

[0133] Meanwhile, when a specific button within the remote control device (200) is pressed, recognition of up, down, left, and right movements may be excluded. That is, when the remote control device (200) moves away from or toward the display unit (180), up, down, left, and right movements may not be recognized, and only forward and backward movements may be recognized. When a specific button within the remote control device (200) is not pressed, only the pointer (205) moves in accordance with the up, down, left, and right movements of the remote control device (200).

[0134] Meanwhile, the movement speed or movement direction of the pointer (205) can correspond to the movement speed or movement direction of the remote control device (200).

[0135] Meanwhile, the pointer in the present disclosure refers to an object displayed on the display unit (180) in response to the operation of the remote control device (200). Accordingly, objects of various shapes other than the arrow shape illustrated in the drawing can be used as the pointer (205). For example, the pointer can be a concept including a point, a cursor, a prompt, a thick outline, etc. In addition, the pointer (205) can be displayed corresponding to one point on the horizontal or vertical axis on the display unit (180), and can also be displayed corresponding to multiple points such as lines or surfaces.

[0136] FIG. 3 is a block diagram of a remote control device that controls a video display device according to one embodiment of the present disclosure.

[0137] Referring to the drawing, the remote control device (200) may include a wireless communication unit (225), a user input unit (235), a sensor unit (240), an output unit (250), a power supply unit (260), a storage unit (270), and a control unit (280).

[0138] The wireless communication unit (225) transmits and receives signals with any one of the image display devices according to the embodiments of the present disclosure described above. Among the image display devices according to the embodiments of the present disclosure, one image display device (100) will be described as an example.

[0139] The remote control device (200) may be equipped with an RF module (221) capable of transmitting and receiving signals with the image display device (100) in accordance with RF communication standards. In addition, the remote control device (200) may be equipped with an IR module (223) capable of transmitting and receiving signals with the image display device (100) in accordance with IR communication standards.

[0140] The remote control device (200) can transmit a signal containing information about the movement of the remote control device (200) to the video display device (100) through the RF module (221).

[0141] In addition, the remote control device (200) can receive a signal transmitted by the video display device (100) through the RF module (221). In addition, the remote control device (200) can transmit commands for power on / off, channel change, volume change, etc. to the video display device (100) through the IR module (223) as needed.

[0142] The user input unit (235) may be composed of a keypad, buttons, a touch pad, or a touch screen. The user can input commands related to the video display device (100) to the remote control device (200) by operating the user input unit (235). If the user input unit (235) has a hard key button, the user can input commands related to the video display device (100) to the remote control device (200) by pushing the hard key button. If the user input unit (235) has a touch screen, the user can input commands related to the video display device (100) to the remote control device (200) by touching a soft key of the touch screen. In addition, the user input unit (235) may be equipped with various types of input means that the user can operate, such as a scroll key or a jog key.

[0143] The user input unit (235) may include a microphone for receiving audio signals such as a user's voice. Voice data collected by the user input unit (235) may be analyzed and processed into a user's control command.

[0144] The sensor unit (240) may be equipped with a gyro sensor (241) or an acceleration sensor (243).

[0145] The gyro sensor (241) can sense information about the movement of the remote control device (200).

[0146] For example, a gyro sensor (241) can sense information about the operation of a remote control device (200) based on the x, y, and z axes. An acceleration sensor (243) can sense information about the movement speed of the remote control device (200). Meanwhile, a distance measuring sensor may be further provided, thereby sensing the distance to the display unit (180).

[0147] The output unit (250) can output a video or audio signal corresponding to the operation of the user input unit (235) or to a signal transmitted from the video display device (100). Through the output unit (250), the user can recognize whether the user input unit (235) is being operated or whether the video display device (100) is being controlled.

[0148] For example, the output unit (250) may be equipped with an LED module (251) that lights up when the user input unit (235) is operated or a signal is transmitted and received with the image display device (100) through the wireless communication unit (225), a vibration module (253) that generates vibration, an audio output module (255) that outputs audio, or a display module (257) that outputs audio.

[0149] The power supply unit (260) supplies power to the remote control device (200). The power supply unit (260) can reduce power waste by stopping the power supply when the remote control device (200) is not moved for a predetermined period of time. The power supply unit (260) can resume the power supply when a predetermined key provided on the remote control device (200) is operated.

[0150] The storage unit (270) can store various types of programs, application data, etc. required for the control or operation of the remote control device (200). If the remote control device (200) wirelessly transmits and receives signals through the video display device (100) and the RF module (221), the remote control device (200) and the video display device (100) can transmit and receive signals through a predetermined frequency band. The control unit (280) of the remote control device (200) can store and refer to information regarding the frequency band through which signals can be wirelessly transmitted and received between the remote control device (200) and the paired video display device (100), etc., in the storage unit (270).

[0151] The control unit (280) controls all matters related to the control of the remote control device (200). The control unit (280) can transmit a signal corresponding to a predetermined key operation of the user input unit (235) or a signal corresponding to the movement of the remote control device (200) sensed by the sensor unit (240) to the video display device (100) via the wireless communication unit (225).

[0152] Meanwhile, the sensor unit (240) may further include a voice sensor (245) (e.g., a microphone) for receiving a user's voice. The user's voice input through the voice sensor (245) may be transmitted to the video display device (100) through the wireless communication unit (225).

[0153] Hereinafter, with reference to FIG. 4, the operation of a video display device according to an embodiment of the present disclosure will be described. FIG. 4 is a flowchart regarding the operation of a video display device according to an embodiment of the present disclosure.

[0154] The storage unit (140) of the video display device (100) may include a personal information database (145) for storing personal information. The personal information may include personal profile information of a user (or viewer) of the video display device (100), schedule / event information, viewing history information, personal profile information of each of the user's acquaintances (e.g., friends or family), and profile images (photos or videos) of the user and each of the acquaintances.

[0155] The personal information DB (145) does not necessarily have to be implemented within the video display device (100), and may be implemented on an external server. That is, the personal information DB (145) may be implemented in at least one of the storage unit (140) and the external server. In this case, the video display device (100) can access the external server to obtain the personal information.

[0156] The information in the above personal information DB (145) may be input directly by the user or may be automatically generated by the use of the video display device (100), or may be received from another external server that stores personal information of the user and / or his / her acquaintances, such as SNS (Social Network Service) [S41].

[0157] The above profile image may be stored for each user and each acquaintance. As the profile image is updated, outdated profile images may not be deleted but may be stored as is. Previously used profile images of the user and each acquaintance may be stored by period. The profile image is an image for visually identifying the user and each acquaintance. It may be a photograph or corresponding image of the user and each acquaintance, or a 2D or 3D avatar, and there is no limitation on the type.

[0158] The control unit (170) of the video display device (100) can learn the personal information through artificial intelligence. Accordingly, the control unit (170) learns the personal information of each user and each acquaintance, and when any information is entered, it can easily infer to whom the entered information belongs. Furthermore, based on the learned personal information, the control unit (170) can also predict past or future personal information (e.g., profile images) that is not recorded in the personal information database (145).

[0159] The control unit (170) can receive a user command through the remote control device (200) [S42]. The user command may be a user's voice command input through the voice sensor (245) of the remote control device (200). The user's voice command may be a natural language command. However, the user command is not limited to the voice command. For example, the user command may be a text command input through a virtual keyboard displayed on the display (180).

[0160] The above control unit (170) can analyze the user's intention according to the user command through artificial intelligence [S43]. The control unit (170) can transmit the user's intention to an external server for artificial intelligence intention analysis and can also receive the user's intention from the external server [S41].

[0161] The analysis of the user's intent may involve extracting information related to the meaning of sentences or texts based on the user's command. To achieve this, artificial intelligence can understand and infer sentence structure, word relationships, and semantic similarities.

[0162] To analyze the user's intention based on natural language understanding, syntactic parsing, semantic parsing, named entity recognition, semantic linking, and sentiment analysis can be performed.

[0163] The above syntax analysis analyzes the structure of a sentence to identify the grammatical roles and relationships between words. This allows for tasks such as part-of-speech tagging and syntax tree generation.

[0164] The above semantic analysis aims to understand and infer the meaning of a sentence. It extracts the meaning of words and identifies relationships and connections within sentences, allowing for the identification of semantically similar words or sentences.

[0165] Named entity recognition can recognize and extract specific types of named entities (such as people, places, and dates) from sentences. This allows for the identification and analysis of important information within a sentence.

[0166] The above semantic connection is intended to analyze the semantic connection between words or objects within a sentence.

[0167] The above sentiment analysis aims to determine whether a sentence or text is positive, negative, or neutral. This allows for understanding and inferring the emotions implicit in the text.

[0168] The above control unit (170) can search for content that matches the user's intention [S44]. The above control unit (170) can also connect to an external server that provides content for searching and downloading the content.

[0169] The above control unit (170) can display a list screen of the searched content on the display (180) [S45].

[0170] The control unit (170) can play content selected by the user on the list screen and display it on the display (180). At this time, the control unit (170) can also display profile pictures of the user and / or the acquaintance. Selection of the content on the list screen can be performed through the operation of the remote control device (200).

[0171] The displayed profile picture may be downloaded from the personal information database (145). Alternatively, the displayed profile picture may be an image synthesis or generated through artificial intelligence based on profile pictures stored in the personal information database (145) [S46]. This will be further explained later.

[0172] Hereinafter, the operation of a video display device according to an embodiment of the present disclosure will be described with reference to FIGS. 5 to 7. FIGS. 5 to 7 illustrate a screen displayed on a video display device according to an embodiment of the present disclosure.

[0173] As illustrated in FIG. 5, for example, the user can input a natural language voice command, such as “Find me a popular drama when I was in my 40s,” into the video display device (100) via the voice sensor. The voice sensor may be of the video display device (100) or of the remote control device (200).

[0174] The above control unit (170) can determine the user's intention of the voice command based on the user's profile information (e.g., current age) and content viewing history.

[0175] The above control unit (170) can search for at least one content that matches the user's intention and control the display (180) to display a list (1000) of the searched content. The list (1000) can include thumbnails (C1 to C7) of each of the searched content.

[0176] Additionally, the control unit (170) can display search criteria (1100) according to the user's intention together with the content list (1000).

[0177] One content (e.g., C3 content) from the above content list (1000) can be selected by the user through the remote control device (200).

[0178] Then, as shown in FIG. 6, the control unit (170) can control the information screen (2000) of the selected content to be displayed on the display (180).

[0179] The above content information screen (2000) may include at least one piece of information about the selected content, such as the name, poster, synopsis, production company, production year, genre, cast, production crew, and rating.

[0180] In addition, the control unit (170) can display a viewing history (2100) in which the user has viewed the selected content and a selection menu (2200) for selecting whether to play the selected content. Although not shown, in addition to the viewing history (2100) and the selection menu (2200), the control unit (170) can also display schedule / event information corresponding to a time period that matches the user's intention.

[0181] The above viewing history (2100) may include information about when the user viewed the content and with whom the user viewed the content.

[0182] A front image of the video display device (100) can be captured during playback of the content by a camera provided to face the front of the video display device (100), and a person in the captured front image can be identified through the artificial intelligence. For this purpose, a profile image of an acquaintance in the personal information DB (145) can be utilized. Through this, the control unit (170) can cumulatively store, in the personal information DB (145), information on the playback time and the person who watched the content together with the user when the content is played. This can be utilized to create the viewing history (2100).

[0183] Meanwhile, the above selection menu (2200) may include a viewing alone option (2210) and a viewing together option (2220).

[0184] When the above-described viewing alone option (2210) is selected by the user through operation of the remote control device (200), the control unit (170) can play the selected content and display the played content (3000) on the display (180), as shown in (7-1) of FIG. 7.

[0185] On the other hand, when the above-mentioned viewing together option (2220) is selected by the user through the operation of the remote control device (200), the control unit (170) can display the selected content (3000) on the display (180) by playing the content, as shown in (7-2) of FIG. 7, and can also display profile images (P1 to P5) of people (i.e., acquaintances) who have watched the content together in the past.

[0186] The profile image displayed for each acquaintance may not be the current profile image, but may be a profile image of each acquaintance from a past time with whom the content was viewed. Accordingly, if the profile image of each acquaintance from a past time is stored in the personal information database (145), the control unit (170) may call up and display the profile image of each acquaintance from a past time.

[0187] However, if there is no profile image of an acquaintance at the past time, the control unit (170) can synthesize or create a new profile image of the past time (e.g., 10 years ago from the present) based on a profile image of the acquaintance at another time (e.g., the present time) stored in the personal information DB (145) through the artificial intelligence. That is, the control unit (170) can newly synthesize or create and display the profile image of the past time by reflecting the time difference (e.g., 10 years) between the other time and the past time in the profile image of the present time. That is, the control unit (170) can newly synthesize or create the profile image of the past time so that the person in the profile image of the past time is the same as the person in the profile image of the present time, but looks 10 years younger.

[0188] In the above, it has been described that when the user selects a content from the content list (1000) displayed according to the user command, the video display device (100) displays an information screen (2000) regarding the selected content and then plays the selected content. However, content may be selected and played only with the user command without displaying at least one of the content list (1000) and the content information screen (2000). This will be further described with reference to FIG. 8. FIG. 8 illustrates a screen displayed on a video display device according to an embodiment of the present disclosure.

[0189] As illustrated in FIG. 8, for example, the user can input a natural language voice command, “I want to see the youngest son of a conglomerate family with Su-ah and his mother,” into the video display device (100) via the voice sensor. Here, “the youngest son of a conglomerate family” refers to the name of a content.

[0190] The above control unit (170) can determine the user's intention of the voice command based on the user's personal information.

[0191] In addition, the control unit (170) can search for and play content that matches the user's intention and control the display (180) to display the played content (4000).

[0192] In addition, the control unit (170) can call up the profile images (P7, P8) of acquaintances (i.e., Sua, Mom) that match the user's intention from the personal information DB (145) and display them together with the reproduced content (4000). The profile images can be the profile images of each acquaintance at the current time.

[0193] If the personal information DB (145) above does not have a profile image of the present time but only a profile image of a past time (e.g., 5 years ago from the present time), the control unit (170) may newly generate or synthesize a profile image of the present time based on the profile image of the past time and display it. That is, the control unit (170) may newly synthesize or generate a profile image of the present time so that the person in the profile image of the present time is the same as the person in the profile image of the past time, but appears 5 years older.

[0194] The above profile image may also be displayed without a multimedia content playback screen. This will be further explained with reference to FIG. 9. FIG. 9 illustrates a screen displayed on a video display device according to one embodiment of the present disclosure.

[0195] As illustrated in FIG. 8, for example, the user can input a natural language voice command such as “How is Sua doing these days?” into the video display device (100) through the voice sensor.

[0196] The above control unit (170) can determine the user's intention of the voice command based on the user's personal information.

[0197] In addition, the control unit (170) can identify an acquaintance that matches the user's intention and obtain personal information of the identified acquaintance that matches the user's intention from the personal information DB (145). If personal information that matches the user's intention is not stored in the personal information DB (145), the control unit (170) can access an external server (e.g., an SNS server) that stores personal information that matches the user's intention and obtain the personal information.

[0198] In addition, the control unit (170) can display a screen (5000) regarding personal information of an acquaintance that matches the user's intention on the display (180).

[0199] The image synthesis or generation described above will be further described with reference to FIG. 10. FIG. 10 illustrates an example of image synthesis or generation according to one embodiment of the present disclosure.

[0200] As illustrated in FIG. 10, the control unit (170) can change, synthesize, or create a past image (P12) or a future image (P14) of a person based on the person's current image (P13) through the artificial intelligence. Alternatively, the control unit (170) can synthesize or create a present image (P13) or a future image (P14) of a person based on the person's past image (P12) through the artificial intelligence. This can be implemented by adjusting facial features and skin tones in a person image, smoothing or roughening the skin, and removing or creating wrinkles.

[0201] Hereinafter, with reference to FIG. 11, we will examine the user login and the user guide for the video display device. FIG. 11 illustrates a screen displayed on the video display device according to one embodiment of the present disclosure.

[0202] As shown in (11-1) of FIG. 11, when entering the setting menu of the video display device (100), the control unit (170) can display a login screen (or account setting screen) (6000) on the display (180).

[0203] The above login screen may display at least one icon (6010, 6020) of a preset account and an icon (6030) for adding an account.

[0204] The user can log in by selecting his / her account icon from among at least one account icon (6010, 6020).

[0205] Alternatively, the user may log in by creating a new account through the add account icon (6030).

[0206] Meanwhile, as illustrated in (11-2) of FIG. 11, the control unit (170) can display a user guide (6100) on the display (180) to guide the user in using the video display device (100). The user guide (6100) can be displayed when the user manipulates a menu and / or when a specific event occurs (e.g., an external device connection event). A guide agent (6110) can be displayed on the user guide (6100). The guide agent (6110) can be, for example, a virtual human.

[0207] However, the control unit (170) can change, create, or synthesize the appearance of the guide agent (6110) so that the appearance of the guide agent (6110) appears to age naturally over time. The change, creation, or synthesis of the appearance is as described in FIG. 10. Accordingly, the user can feel as if the image display device (100) is a companion device while watching the appearance changes of the guide agent (6110).
